Point and Stand-off Microwave-Induced Thermal Emis
Agency / Branch:
DOD / ARMY
The Joint Services have a need for a short range, active stand-off capability to detect surface areas that may be contaminated with chemical, biological, or explosive (CBE) materials and to classify the nature of the contaminant. Recently, laser-induced thermal emission (LITE) measurements have shown promise for performing chemical analysis of thin layers on surfaces. We propose to conduct a series of systematic experiments to demonstrate the usefulness of transient thermal emission spectroscopy (TIRES) for detection of CBE materials on surfaces. Bodkin Design and Engineering has developed multi-spectral and hyperspectral imaging systems for wavebands from visible to long wavelength infrared (LWIR) and which are particularly suited to monitor transient events. In phase 1, we will determine the optimal settings (microwave heater power, dwell time, detection wavelength ranges, etc.) needed to maximize contrast between the surface contaminant and the underlying background and thereby maximize the probability of detection. The results will lead to a design for a breadboard prototype to be built in phase 2. In Phase 2, we will perform a comprehensive engineering design analysis of the prototype in order to predict baseline performance, project detection limits, and develop a set of preliminary Receiver Operational Characteristic (ROC) curves. We will then optimize the design, build it and test it using simulated CBE materials.
